If you look at yours, you will > hopefully find that there :-) You want the short or long answer? ;) The first 3 lines of the /etc/hosts file should always read: # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 <yourhostnamehere> localhost.localdomain localhost Of course <yourhostnamehere> needs to be replaced with the hostname of your box if you called your host anything other than localhost in the install... That is how the resolution from the hostname to the IP address is done. The loopback device lo with its IP address is setup in /etc/sysconfig/network-scripts/ifcfg-lo That way the interface will come up even without the /etc/hosts entry there. The unix95 standard defines that localhost must be resolved - and all programmers I know just assume that this will work. Its kinda like when you buy a new car, you kinda assume it has a steering wheel. You'll see a lot of newbee users change that at some point in time - and that has all kinds of fun results. So if you hear that something strange network related fails, its a good idea to check that file first to make sure its nothing trivial than that... Anyway, in the end the short answer to your question is that there was nothing in the log files that pointed to it directly, its was just something from experience that made me ask to check it... and besides that, either I missed an email or something but I haven't got the confirmation yet that the tnslistener actually works now...
